The results show that the efficiency Figure 15 by adjusting worth of of resistive load. The results show that the efficiency on the inverter is larger than 92 when the energy ranges from 24 W to 222 W. Especially of inverter is is larger than 92 when the power ranges from 24 W to 222 W. Especially, thethe inverter bigger than 92 when the power ranges from 24 W to 222 W. Especially, the efficiency isis bigger than 97 when the output power is bigger than 50 W. It truly is apparent efficiency bigger than 97 when the output power is larger than 50 W. the apparent the efficiency is bigger than 97 when the output energy is larger than 50 W. It is actually apparent thatthe inverter includes a high efficiency over a wide load variety. the inverter includes a higher efficiency over a wide load range. that the inverter has a high efficiency thatThe partnership between the technique efficiency and output power is accomplished in Fig-Figure 15.
